Quasar-Mode Feedback in Nearby Type 1 Quasars: Ubiquitous Kiloparsec-Scale Outflows and Correlations with Black Hole Properties

Abstract

The prevalence and properties of kiloparsec-scale outflows in nearby Type 1 quasars have been the subject of little previous attention. This work presents Gemini integral field spectroscopy of ten Type 1 radio-quiet quasars at $z < 0.3$ . The excellent image quality, coupled with a new technique to remove the point spread function using spectral information, allow the fitting of the underlying host on a spaxel-by-spaxel basis. Fits to stars, line-emitting gas, and interstellar absorption show that 100% of the sample host warm ionized and/or cool neutral outflows with spatially-averaged velocities ( $⟨ v_{98%} ⟩ \equiv ⟨ v + 2 σ ⟩$ ) of 200-1300 km/s and peak velocities (maximum $v_{98%}$ ) of 500-2600 km/s. These minor-axis outflows are powered primarily by the central AGN, reach scales of 3-12 kpc, and often fill the field of view. Including molecular data and Type 2 quasar measurements, nearby quasars show a wide range in mass outflow rates ( $d M / d t = 1$ to $>$ 1000 M $_{⊙}$ /yr) and momentum boosts [( $c$ $d p / d t$ )/L $_{AGN}$ = 0.01-20]. After extending the mass scale to Seyferts, $d M / d t$ and $d E / d t$ correlate with black hole mass ( $d M / d t \sim M_{BH}^{0.7 \pm 0.3}$ and $d E / d t \sim M_{BH}^{1.3 \pm 0.5}$ ). Thus, the most massive black holes in the local universe power the most massive and energetic quasar-mode winds.
